453-acre lake near Na h-Eileanan an Iar. The lake tops out around 18 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Loch nan Geireann runs 452 acres with 9.1 miles of edge. That shoreline is heavily fingered (development index 3.1) — bays, points and pockets everywhere, which multiplies the fishable edge. About 95% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
Early season brown trout use the shallows, holding in 2 to 18 ft. Even in summer they hold at 5 to 18 ft; winter keeps them in 3 to 18 ft. Put Break off the point first on the milk run — a drop-off near 8 ft that grades prime for summer. In summer the feeding windows fall in after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.

| Summer | 5 to 18 ft | night & dawn | Break off the point (8 ft) | Spoon at the thermocline, Deep stickbait (night) |

Spring puts european perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 5 to 18 ft, wintering in 5 to 18 ft. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.

Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
